METAL HOOP.

Application filed August 15,

Specification of Letters Patent.

Patented Aug. 7, 1906.

1904:. Serial No. 220.840.

To all whom it may concern:

Be it known that I, JAMES E. WRIGHT, a

Bay City, in the county of Bay and State of Michigan, have invented certain new and use ful Improvements in Metal Hoops; and. I do and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention is a metal hoop for barrels, casks, and similar packages.

The objects of the invention are to produce a hoop made of a band of metal shaped in such a way that the band may be made very thin and yet have great strength to resist both the tension produced by driving and the crushing force due to the force of the drivingtool upon the upper edge of the hoop, so that the hoop may be driven tight upon the barrel upper or driving edge of the hoop.

The construction of the hoop is such that no extra stiffening, or reinforcing means are required, the necessary strength to resist the crushing in driving being attained by the form of the beaded upper edge of the hoop.

With these and other objects in view the invention consists in the device illustrated in the accompanying drawings, in ,which Figure 1 is a art sectional view of a barrel with a hoop in p ace, showing the relativeposition of the hoop-and driving-tool while the place. Fig. 3 is an enlarged sectional detail of the hoop.

As is clearly shown in the drawings, the hoop consists in a strip or band of metal 1, having its upper part 2 bent outwardly, downwardly, and inwardly to form a beaded edge.

The essential feature of this invention lies in the construction and mode of operation of the beaded edge. It will be seen from Figs. 2 and 3 that by bending the upper portion band bears completely t oughout its area upon the barrelstaves. The greatest strength to resist distortion of the barrel when it is dropped or a heavy blow is dealt on the ends of the staves, tending to slide them past each other, is attained when the distance 1 is greatest, and the greatest economy of material is attained when the amount of material 1 used in the bead 2 is' least when compared with that used in the part 1 Therefore I I prefer in practice to make the bead 2 of relatively small diameter, leavingas much as possible of the width of the band to form the part 1 which, as has just been explained, imparts trussstrength to the barrel. In order to prevent distortion of the upper edge of the hoop, which tends to occur when the hoop is driven down tight by means of a hand or other drivingtool 3, as shown in Fig. 1, I form the loop 2 so that its cross section takes the form of an arch, the upper end of which is integral with the flat part 1. and the lower end 2 of which is bent inwardly, so as to butt against the outer face of the part 1*. By th sconstruction it is found in ractice that extremely heavy blows may e delivered upon the hoop in driving, as indicated by the arrows in Figs. 1 and 3, without crushing or distorting the upper edge of the hoop. fact, I have found by practical experience that by this curved or arched construction (in which the upper end of the arch is integral with the body of the hoop and the lower end of the arch butts against the hoop-body) any ordinary blow on the driving edge will not in the least distort the upper edge of the hoop even if the hoop be made of extremely thin metal.

By this construction I produce a hoop having a smoothupper driving-surface, smooth outer face that will not catch on obstructions, and an upper hollow driving edge that re quires no reinforcing-wires or other supports. This hoop has extensive bearing area on the barrel, and although it may be made of extremely thin metal, being, therefore, much cheaper to manufacture, it combines with lightness of materi a1 great stren th and great power ofresisting distortion in driving.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. As an article of manufacture, a hoop comprising a flat body portion, the entire inner transverse periphery of which engages the receptacle to which it is a .vlied, and an approximately semicylindricai ead formed on the upper edge of the body portion to a1- ford a broad, hollow, drivingedge, the bead extending outwardly away from the body portion, thence downwardly and thence inwardly in an approximately straight line to- Ward the body portion constituting a hollow unreinforced arch, the inwardly-extending end of the arch abutting directly against the outer periphery of the body portion at substantially right angles thereto to brace the arch and-resist distortion by the impact of a driving means. 7

2. As an article of manufacture, a hoop comprising a flat body portion, the entire inv ialpkproximately semicylindrica edge of the bead abutting against ner transverse peri hery of which engages the receptacle to W -ch it is a plied, and an orcedbead extending along the upper edge of the body portion and of apredetermined conformation'to resist breaking down under the impact of a driving means, the free lower the body hollow, um'eprevent a slipping or a distortion of the bead..

In testimony whereof I afiix my signature in presence of two witnesses. 4
